Description

Antriebsstrang für Hybridantriebe sowie Torsionsdämpfer Powertrain for hybrid drives and torsion dampers
Die Erfindung betrifft einen Antriebsstrang für Hybridantriebe sowie einen Torsionsdämpfer.The invention relates to a drive train for hybrid drives and a torsion damper.
Zur Reduzierung von Torsionsschwingungen im Antriebsstrang eines Hybridantriebs werden in der Praxis ein oder mehrere Torsionsdämpfer (TD) eingesetzt. Eine typische Anordnung besteht aus einem TD zwischen der Motordrehmasse und der E-Maschine und einem weiteren TD zwischen E-Maschine und Getriebeeingangswelle. Dadurch entsteht ein 3-Massenschwingungssystem, bei dem die Resonanz der E-Maschine in den Frequenzbereich fällt, der vor allem von 4-Zylindermotoren durch die Hauptordnung (2. Ordnung) angeregt wird. Dies führt im niedertourigen Fahrbereich zu störenden Brummüberhöhungen.To reduce torsional vibrations in the drive train of a hybrid drive, in practice, one or more torsional dampers (TD) are used. A typical arrangement consists of a TD between the engine mass and the electric motor and another TD between the electric motor and the transmission input shaft. This creates a 3-mass vibration system in which the resonance of the electric motor falls within the frequency range, which is mainly excited by 4-cylinder engines through the main order (2nd order). This leads to annoying hum in the low-speed driving range.

In dem in Fig. 1 gezeigten Ersatzschaltbild einer besonders bevorzugten ersten Ausführungsform eines erfindungsgemäßen Antriebsstrangs 100 sind eine Brennkraftmaschine 102 und eine E-Maschine 104 vorgesehen, um über ein Schaltgetriebe 106 eine Abtriebswelle 108 anzutreiben. Die Brennkraftmaschine 102 ist vorzugsweise ein 4-, 5- oder 6-Zy!inder Otto- oder Dieselmotor. Die E-Maschine 104 ist ein Aggregat welches sowohl einen Motor- als auch einen Generatorbetrieb erlaub. Das Schaltgetriebe 106 ist ein Getriebe mit fünf, sechs oder sieben Vorwärtsgängen. Ein Rückwärtsgang ist nicht zwingend vorzusehen, da eine Rückwärtsfahrt über die E- Maschine 104 darstellbar ist. Wenn der Antrieb über die Brennkraftmaschine 102 erfolgt, stellen diese sowie die E-Maschine 104 und das Schaltgetriebe 106 ein Drei-Massen- System dar.In the equivalent circuit shown in Fig. 1 of a particularly preferred first embodiment of a drive train 100 according to the invention are a Internal combustion engine 102 and an electric motor 104 is provided to drive via a gearbox 106, an output shaft 108. The internal combustion engine 102 is preferably a 4, 5 or 6 cylinder in the Otto or Diesel engine. The electric machine 104 is an engine that allows both engine and generator operation. The transmission 106 is a transmission with five, six or seven forward gears. A reverse gear is not mandatory, since a reverse drive on the electric motor 104 can be displayed. When driven by the engine 102, these as well as the electric motor 104 and the manual transmission 106 constitute a three-mass system.
Um Drehungleichförmigkeiten der Brennkraftmaschine 102 auszugleichen, ist ein Torsionsdämpfer 110 gemäß einer besonders bevorzugten ersten Ausführungsform der Erfindung vorgesehen, dessen Eingangsseite 112 mit einer Kurbelwelle (nicht gezeigt) der Brennkraftmaschine 102 verdrehfest verbunden ist und dessen Ausgangsseite 114 verdrehfest an eine Eingansseite 116 einer Kupplung 118 angeschlossen ist. Die Kupplung 118 ist als Nasskupplung ausgeführt. Eine Ausgangsseite 120 der Kupplung 118 ist verdrehfest mit einer Welle 122 der E-Maschine 104 verbunden.To compensate for rotational irregularities of the internal combustion engine 102, a torsional damper 110 is provided according to a particularly preferred first embodiment of the invention, the input side 112 with a crankshaft (not shown) of the internal combustion engine 102 is rotationally connected and its output side 114 rotationally connected to an input side 116 of a coupling 118 is. The clutch 118 is designed as a wet clutch. An output side 120 of the clutch 118 is rotationally connected to a shaft 122 of the electric motor 104.
Der Torsionsdämpfer 110, der in Fig. 2 in einem vereinfachten Schnitt gezeigt ist, ist als ein erstes Feder- und Dämpfungssystem 124 nach Art eines Zwei-Massen- Schwungrades aufgebaut, wobei eine erste Rotationsmasse 126 an der Ausgangsseite 114 angeordnet ist. An dieser ersten Rotationsmasse 126 stützt sich eine Käfigeinrichtung 128 mit mehreren Käfigen130 ab, wobei diese Käfige 130 der Aufnahme von Druckfedern 132 dienen. An ihrer einen Seite stützen sich die Duckfedern 132 an dem jeweiligen Käfig 130 ab, und mit ihrer anderen Seite stützen sich die Duckfedern 132 über eine Zentralscheibe 134 und eine Nabe 136 an einer Welle 138 ab, wobei die Welle 138 als Teil der Kupplung 118 ausgebildet sein kann.The torsion damper 110, which is shown in a simplified section in FIG. 2, is constructed as a first spring and damping system 124 in the manner of a two-mass flywheel, wherein a first rotational mass 126 is arranged on the output side 114. At this first rotational mass 126 a cage device 128 is supported with a plurality of cages 130, these cages 130 serving to receive compression springs 132. On one side, the duck feathers 132 are supported on the respective cage 130, and on the other side, the duck feathers 132 are supported on a shaft 138 via a central disk 134 and a hub 136, the shaft 138 being formed as part of the coupling 118 can be.
Der Torsionsdämpfer 110 weist ferner eine Fliehkraftpendeleinrichtung 140 auf, welche auch als Fliehkraftpendel bezeichnet werden kann. Diese Fliehkraftpendeleinrichtung 140 weist Pendelmassen 142, 144 auf, die in Kurvenbahnen im Fliehkraftfeld pendeln. In Fig. 2 ist gezeigt, dass die Fliehkraftpendeleinrichtung 140 radial außerhalb der Käfigeinrichtung 128 mit den Druckfedern 132 in einer axial gleichen Lage angeordnet ist. Allerdings befinden sich sowohl die FNehkraftpendeleinrichtung 140 als auch die Käfigeinrichtung 128 mit den Druckfedern 132 innerhalb der durch die erste Rotationsmasse 126 bestimmten Kontur.The torsion damper 110 further includes a centrifugal pendulum device 140, which may also be referred to as centrifugal pendulum. This centrifugal pendulum device 140 has pendulum masses 142, 144 which oscillate in curved paths in the centrifugal force field. In Fig. 2 it is shown that the centrifugal pendulum device 140 is disposed radially outside of the cage device 128 with the compression springs 132 in an axially identical position. However, both the FNehkraftpendeleinrichtung 140 and the cage device 128 with the compression springs 132 are within the determined by the first rotational mass 126 contour.
Die Wirkungsweise des gezeigten Antriebsstrangs ist folgende:The mode of action of the powertrain shown is the following:
Ein von der Brennkraftmaschine 102 erzeugtes Drehmoment mit überlagertem Wechselmoment wird zunächst durch die and er ersten Rotationsmasse 126 (Schwungrad) befestigte Käfigeinrichtung 128 (Federführungsbleche) auf die Druckfedern 132 des Torsionsdämpfers 110 übertragen und von den Federn 132 auf die mit der Welle 138 zur nassen Anfahrkupplung (NAK) befestigte Nabe 136 weitergeleitet. Diese Nabe 136 und die mit dieser verbundene Zentralscheibe 134 sind im Außendurchmesser so gestaltet, dass radial außerhalb des Federsatzes ausreichend Bauraum vorhanden ist, um die Fliehkraftpendeleinrichtung 140 (das Fliehkraftpendel) daran zu befestigen. Dadurch wird erreichet, dass das vom Motor erzeugte Wechselmoment durch den Federsatz bereits erheblich reduziert wird, und dass das Fliehkraftpendel einen maximalen Wirkradius besitzt und damit ein großes Gegenmoment zu dem nach dem Torsionsdämpfer noch vorhandenen Wechselmoment aufbringen kann. Da die Nabe 136 bei geschlossener Kupplung 118 (NAK) direkt mit der E-Maschine 104 verbunden ist, wirkt das Gegenmoment direkt auf die E-Maschine 104 und kann damit die durch die Resonanz der E-Maschine 104 hervorgerufenen Schwingungen deutlich reduzieren.A generated by the internal combustion engine 102 torque with superimposed alternating torque is first transmitted by the first rotational mass 126 (flywheel) mounted cage device 128 (spring guide plates) on the compression springs 132 of the torsion damper 110 and from the springs 132 to the shaft 138 to the wet starting clutch (NAK) attached hub 136 forwarded. This hub 136 and connected to this central disc 134 are designed in outer diameter so that radially outside the spring set sufficient space is available to the centrifugal pendulum device 140 (the centrifugal pendulum) to attach it. This ensures that the alternating torque generated by the engine is already significantly reduced by the spring set, and that the centrifugal pendulum has a maximum effective radius and thus can muster a large counter-torque to the still existing after the torsional change moment. Since the hub 136 is directly connected to the electric motor 104 when the clutch 118 (NAK) is closed, the counter torque acts directly on the electric motor 104 and can thus significantly reduce the vibrations caused by the resonance of the electric motor 104.
Es sei noch erwähnt, dass zwischen der E-Maschine 104 und dem Getriebe 106 ein zweites Feder- und Dämpfungssystem 146 angeordnet ist.It should be noted that between the electric motor 104 and the gear 106, a second spring and damping system 146 is arranged.
Der anhand der Fig. 3 gezeigte Antriebsstrang 200 gemäß einer besonders bevorzugten zweiten Ausführungsform der Erfindung sowie der darin vorgesehene, in Fig. 4 gezeigte Torsionsdämpfer 210 gemäß einer besonders bevorzugten zweiten Ausführungsform der Erfindung unterscheiden sich von der jeweils ersten Ausführungsform nur in Details. Daher sind zur Beschreibung Bezugszeichen verwendet, die gegenüber der jeweils ersten Ausführungsform um 100 erhöht sind. Auf die entsprechende Beschreibung wird hiermit ausdrücklich Bezug genommen und verwiesen.The drive train 200 shown in FIG. 3 according to a particularly preferred second embodiment of the invention and the therein provided, shown in Fig. 4 torsion damper 210 according to a particularly preferred second embodiment of the invention differ from the respective first embodiment only in detail. Therefore, reference numerals are used for description, which are increased by 100 with respect to the respective first embodiment. The corresponding description is hereby incorporated by reference and referenced.
Wie bei der ersten Ausführungsform sind auch in dem in Fig. 3 gezeigten Antriebsstrang 200 eine Brennkraftmaschine 202 und eine E-Maschine 204 vorgesehen, die dazu dienen, über ein Schaltgetriebe 206 eine Abtriebswelle 208 anzutreiben. Die Brennkraftmaschine 202 ist vorzugsweise ein 4-, 5- oder 6-Zylinder Otto- oder Dieselmotor. Die E-Maschine 204 ist ein Aggregat welches sowohl einen Motor- als auch einen Generatorbetrieb erlaub. Das Schaltgetriebe 206 ist ein Getriebe mit fünf, sechs oder sieben Vorwärtsgängen. Ein Rückwärtsgang ist nicht zwingend vorzusehen, da eine Rückwärtsfahrt über die E-Maschine 204 darstellbar ist. Wenn der Antrieb über die Brennkraftmaschine 202 erfolgt, stellen diese sowie die E-Maschine 204 und das Schaltgetriebe 206 ein Drei-Massen-System dar.As in the first embodiment, an internal combustion engine 202 and an electric motor 204 are provided in the powertrain 200 shown in FIG serve to drive via a gearbox 206, an output shaft 208. The internal combustion engine 202 is preferably a 4, 5 or 6 cylinder petrol or diesel engine. The e-machine 204 is an aggregate which allows both motor and generator operation. The manual transmission 206 is a transmission with five, six or seven forward gears. A reverse gear is not mandatory, since a reverse drive on the electric motor 204 can be displayed. When driven by the engine 202, these as well as the electric motor 204 and the manual transmission 206 constitute a three-mass system.
Um Drehungleichförmigkeiten der Brennkraftmaschine 202 auszugleichen, ist ein Torsionsdämpfer 210 gemäß einer besonders bevorzugten ersten Ausführungsform der Erfindung vorgesehen, dessen Eingangsseite 212 mit einer Kurbelwelle (nicht gezeigt) der Brennkraftmaschine 202 verdrehfest verbunden ist und dessen Ausgangsseite 214 verdrehfest an eine Eingansseite 216 einer Kupplung 218 angeschlossen ist. Die Kupplung 218 ist als Nasskupplung ausgeführt. Eine Ausgangsseite 220 der Kupplung 218 ist verdrehfest mit einer Welle 222 der E-Maschine 204 verbunden.To compensate for rotational irregularities of the internal combustion engine 202, a torsion damper 210 is provided according to a particularly preferred first embodiment of the invention, the input side 212 with a crankshaft (not shown) of the internal combustion engine 202 is rotationally connected and its output side 214 rotationally connected to an input side 216 of a clutch 218 is. The clutch 218 is designed as a wet clutch. An output side 220 of the clutch 218 is rotationally connected to a shaft 222 of the electric motor 204.
Der Torsionsdämpfer 210, der in Fig. 4 in einem vereinfachten Schnitt gezeigt ist, ist als ein erstes Feder- und Dämpfungssystem 224 nach Art eines Zwei-Massen- Schwungrades aufgebaut, wobei eine erste Rotationsmasse 226 an der Eingangsseite 212 angeordnet ist.The torsion damper 210, which is shown in a simplified section in FIG. 4, is constructed as a first spring-and-damper system 224 in the form of a two-mass flywheel with a first rotational mass 226 disposed on the input side 212.
Auch die zweite Ausführungsform weist eine Käfigeinrichtung 228 mit mehreren Käfigen 230 auf, wobei diese Käfige 230 der Aufnahme von Druckfedern 232 dienen. An ihrer einen Seite stützen sich die Duckfeder 232 an dem jeweiligen Käfig 230 ab. Im Unterschied zur ersten Ausführungsform stützen sich die Federn 232 jedoch mit ihrer anderen Seite an einem Zentralring 250, wobei dieser Zentralring 250 mit der ersten Rotationsmasse 226 in Wirkverbindung ist. Dementsprechend stützt sich im Unterschied zur ersten Ausführungsform bei der zweiten Ausführungsform die Käfigeinrichtung 228 ggf. über eine Nabe an einer Welle 238 ab, wobei die Welle 238 als Teil der Kupplung 218 ausgebildet sein kann.The second embodiment also has a cage device 228 with a plurality of cages 230, these cages 230 serving to receive compression springs 232. On its one side, the duckbill 232 is supported on the respective cage 230. In contrast to the first embodiment, however, the springs 232 are supported with their other side on a central ring 250, said central ring 250 is in operative connection with the first rotational mass 226. Accordingly, in contrast to the first embodiment in the second embodiment, the cage device 228 is optionally supported via a hub on a shaft 238, wherein the shaft 238 may be formed as part of the coupling 218.
Der Torsionsdämpfer 210 weist ferner eine Fliehkraftpendeleinrichtung 240 auf, welche auch als Fliehkraftpendel bezeichnet werden kann. Diese Fliehkraftpendeleinrichtung 240 weist Pendelmassen 242, 244 auf, die in Kurvenbahnen im Fliehkraftfeld pendeln. Daher steigt die Frequenz des Pendels mit der Drehzahl an und kann über den ganzen Drehzahlbereich der Drehungleichförmigkeit tilgen. In Fig. 4 ist gezeigt, dass die Fliehkraftpendeleinrichtung 240 radial außerhalb der Käfigeinrichtung 228 mit den Druckfedern 232 in einer axial gleichen Lage angeordnet ist. Allerdings befänden sich sowohl die Füehkraftpendeleinrichtung 240 als auch die Käfigeinrichtung 228 mit den Druckfedern 232 innerhalb der durch die erste Rotationsmasse 226 bestimmten Kontur.The torsion damper 210 further includes a centrifugal pendulum device 240, which may also be referred to as a centrifugal pendulum. This centrifugal pendulum device 240 has pendulum masses 242, 244, which oscillate in curved paths in the centrifugal force field. Therefore, the frequency of the pendulum increases with speed and can cancel the rotational nonuniformity over the entire speed range. In Fig. 4 it is shown that the centrifugal pendulum means 240 is disposed radially outside of the cage means 228 with the compression springs 232 in an axially identical position. However, both the Füehkraftpendeleinrichtung 240 and the cage device 228 with the compression springs 232 within the determined by the first rotational mass 226 contour.
